Features 0.42 or 0.45 conversion ratio, so if it is placed on a 35-80mm lens, you will have a 15-34mm lens, that covers all wide variations, from what we know as fisheye effect (180 degrees view) to a normal wide-angle (just by playing with your zoom).

Please note that the examples shows focal legths already converted to film standard. The results vary depending on the lens this is placed onto, the listing asumes you will use it with the standard camera plus lens kit. A black circle known as vignetting might occur if you combine the lens with filters or step-down adapters. This is just part of the effect.

Macro mode:
This is a lens that will enable to take close-up pictures. Onto the standard lens above you will be able to take sharp pictures as close as 50mm from the subject (perfect for miniatures, coins, insects, flowers, etc..).
